Detailed explanation-1: -An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.
Detailed explanation-2: -IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
Detailed explanation-3: -Intelligence Quotient (IQ) is the score you get on an intelligence test. Originally, it was a quotient (a ratio): IQ= MA/CA x 100 [MA is mental age, CA is chronological age]. Today, scores are calibrated against norms of actual population scores.
Detailed explanation-4: -Critical interpretation of full-scale IQ scores. To further simplify it: An IQ of 75 means that an 8-year-old child will function intellectually overall at 75% of the average 8-year-old’s intellectual functioning ie, at an average of a 6-year-old level.
Detailed explanation-5: -Hence, we can conclude that the IQ of a 25-year-old boy whose mental age is 16 will be 64.
